My personal experience in the past four decades is that the most antisemitic people in the USA are African Americans, not rich white guys who belong to all white country clubs and sit around in lounge chairs telling 'Jew Jokes'. The most anti Israel attitudes and positions come from Democrats.

My recollection is 1984; the same year that Jesse Jackson and his Hyme-town remark made the news for a while!
